## Additional Noise can be added to audio.wav fiel to test the ASR model and step 2-4 is repeated

# Types of Plots 1. Boxplot of accuracy rate for each phoneme across selected TIMIT files 2. Stacked boxplot of accuracy rate across varying added noise 3. Time/frequency Plot any given TIMIT audio showing the timing/phoneme which was incorrected predicted (substitution and deletion only)
